Apple’s lawyers warned it could quit the UK market if a court forces the company to pay a ‘commercially unacceptable’ fee for the technology used in its iPhones.

And:

Apple issued the warning as part of a court battle with UK patent holder Optis Cellular Technology.

And:

Optis is suing Apple for patent infringement after the iPhone maker refused to pay licence fees worth a possible $7billion for using ‘standardised’ smartphone technology in its products.

A High Court judge ruled last month that Apple had infringed two Optis patents, which help iPhones connect to the 3G and 4G networks.

The article is a hot take, but interesting nonetheless. If the follow-on court proceedings levy more in fines than Apple can make in profits in the UK, what choice would they have?
